i'm using a Logitech keyboard and WinXp SP2
the Numeric keypad only works in Num-Lock mode with C::B
the navigation keys are not working too.
the navigation keys are working with other applications
This may be a problem with wxScintilla translation of the WXK_NUMPAD_{RIGHT|LEFT|UP|DOWN} keys codes etc.
Try this. Move your cursor into the projects window with a large project loaded so that you can move up and down the tree items.
Do the keypad navigation keys work now? If so (as is my case) the keys work for a wxWidgets control, but not for a wxStyledTextCtrl.
